Using climate change as a prototype motivating example, this paper analyzes the implications of structural uncertainty for the economics of low-probability high-impact catastrophes. The paper shows that having an uncertain multiplicative parameter, which scales or amplifies exogenous shocks and...

I construct a novel measure of household uncertainty based on survey data for European countries. I show that household uncertainty shocks do not universally behave like negative demand shocks. Notably, household uncertainty shocks are largely inflationary in Europe. Further analysis, including...

We introduce a novel measure of uncertainty that is based on a business survey in which firms are asked directly how certain or uncertain they are. So far the literature has tried to capture economic uncertainty indirectly by means of expectation errors or the extent of disagreement. Our direct...
